Parameters 341
40
40 Process PID set 1
Parameter values for process PID control.
The drive contains a single active PID controller for process
use, however two separate complete set-ups can be
programmed and stored.
The first set is made up of parameters 40.07…40.56*, the
second set is defined by the parameters in group 41 Process
PID set 2. The binary source that defines which set is used is
selected by parameter 40.57 PID set1/set2 selection.
See also the control chain diagrams on pages 658 and 659.
*The remaining parameters in this group are common for both
sets.
40.01 Process PID output
actual
Displays the output of the process PID controller. See the
control chain diagram on page 659.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
-
-32768.00 …
32767.00
Process PID controller output. 1 = 1 unit
40.02 Process PID
feedback actual
Displays the value of process feedback after source
selection, mathematical function (parameter 40.10 Set 1
feedback function), and filtering. See the control chain
diagram on page 658.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
-
-32768.00 …
32767.00
Process feedback. 1 = 1 unit
40.03 Process PID
setpoint actual
Displays the value of process PID setpoint after source
selection, mathematical function (40.18 Set 1 setpoint
function), limitation and ramping. See the control chain
diagram on page 659.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
-
-32768.00 …
32767.00
Setpoint for process PID controller. 1 = 1 unit
40.04 Process PID
deviation actual
Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted by
parameter 40.31 Set 1 deviation inversion. See the control
chain diagram on page 659.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
-
-32768.00 …
32767.00
PID deviation. 1 = 1 unit
40.05 Process PID trim
output act
Displays the trimmed reference output. See the control chain
diagram on page 659.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
